Footwear upper portion



FIG. 1 is a right side view of a footwear upper portion, showing my new design; and,

FIG. 2 is a top view thereof.

The solid line segment substantially mid-height of the design in FIG. 1, extending substantially horizontally the full length of the design in FIG. 1, is intended to be representative either of edges of respective pieces of material, overlying other pieces of a material or simply a design effect created by application of such line by drawing or created by thermoforming.

The broken line showing in the figures of the sole and other parts of the footwear upper portion is for illustrative purposes only and forms no part of the claimed design. Any surfaces that are not shown form no part of the claimed design. 

The ornamental design for a footwear upper portion, as shown and described.
